Seed cart

Abstract

A vehicle for transporting bulk seed containers and for transferring seed from the bulk seed containers to a seed planting machine includes a frame; a number of bulk seed container supports attached to the frame, each bulk seed container support supporting a bulk seed container; a feed tube connected to each of the bulk seed container supports, each feed tube engaging a bulk seed container; a delivery tube connected to each feed tube; a funnel commonly connected to the delivery tubes; an auger tube connected to the funnel and an auger to transfer seed to a seed planting machine.

The invention claimed is: 
     
       1. A seed cart for transporting bulk seed containers and for transferring seed from the bulk seed containers to a seed planting machine, the seed cart comprising:
 a frame; 
 a plurality of bulk seed container supports attached to the frame, each of the plurality of bulk seed container supports being adapted to support a bulk seed container of said bulk seed containers; 
 a feed tube connected to each of the plurality of bulk seed container supports, each feed tube being configured to engage a bulk seed container of said bulk seed containers when the container is supported on a corresponding bulk seed container support of said plurality of bulk seed container supports; 
 a delivery tube connected to each feed tube; 
 a funnel connected to the plurality of delivery tubes to receive seed from the delivery tubes; and 
 an auger tube having a first end connected to the funnel and a second end, the auger tube further comprises a first section connected to the funnel and a second section pivotally connected to the first section so that the second section is pivotable between an operational position in which interiors of the first and second sections are in fluid communication with each other, and a transport position in which a gap is formed between the first and second sections; 
 an auger positioned in the first section of the auger tube; and 
 a motor connected to rotate the auger so that the auger is operable in a first rotational direction and in a second rotational direction. 
 
     
     
       2. The seed cart of  claim 1  wherein operation of the motor in the first rotational direction causes any seed in the first section of the auger tube to move toward the second section of the auger tube for dispensing, and operation of the motor in the second rotational direction causes any seed in the second section to move toward the first section. 
     
     
       3. The seed cart of  claim 1  wherein operation of the motor in the first rotational direction causes any seed in the auger tube to move in an upward direction in the auger tube, and operation of the motor in the second rotational direction permits any seed in the second section to move in a downward direction toward the first section by gravity. 
     
     
       4. The seed cart of  claim 1  additionally comprising a user-operable control effective to cause a change in the rotational direction of the motor between the first rotational direction and the second rotational direction. 
     
     
       5. A seed cart for transporting bulk seed containers and for transferring seed from the bulk seed containers to a seed planting machine, the seed cart comprising:
 a frame; 
 a plurality of bulk seed container supports attached to the frame, each of the plurality of bulk seed container supports being adapted to support a bulk seed container of said bulk seed containers; 
 a feed tube connected to each of the plurality of bulk seed container supports, each feed tube being configured to engage a bulk seed container of said bulk seed containers when the container is supported on a corresponding bulk seed container support of said plurality of bulk seed container supports; 
 a delivery tube connected to each feed tube; 
 a funnel connected to the plurality of delivery tubes to receive seed from the delivery tubes; and 
 an auger tube having a first end connected to the funnel and a second end, the auger tube further comprises a lower section connected to the funnel and an upper section pivotally connected to the lower section so that the upper section is pivotable between an operational position in which interiors of the lower and upper sections are in fluid communication with each other, and a transport position in which a gap is formed between the lower and upper sections; 
 an auger positioned in the lower section of the auger tube; 
 a motor connected to rotate the auger so that the auger is operable in a first rotational direction and in a second rotational direction; and 
 a user-operable control effective to cause a change in the rotational direction of the motor between the first rotational direction and the second rotational direction; 
 wherein operation of the motor in the first rotational direction causes any seed in the lower section of the auger tube to move toward the upper section of the auger tube for dispensing, and operation of the motor in the second rotational direction causes any seed in the upper section to move toward the lower section.
